The Rotary Dryer made by our company is mainly used in building materials, metallurgy, chemical plant, drying of limestone slag for cement plant, coal powder, slag, claystone etc. The dryer is formed by rotary body, lifting blade, driving device, supporting device, sealing ring, etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and is convenient for operation.

Rotary dryer working principle:

Rotary dryer adopts direct flow type of heating with heat soure from firing unit. The material to be dried is pushed back immindiately by spiral board when enters the shell from feeding tank and feeding chute. Because the dryer is installed in slope, material flows to the back end under gravity and rotation force, meanwhile, it is lifted by board repeatedly and thrown down accordingly, which make the material form even curtain, and exchange heat sufficiently with inner the heat flow. In the end, water in the material is dried by repeatedly scattering.
